探讨妇科腹腔镜手术气腹和体位(T位)对呼吸功能的影响程度。方法:将患者80例随机分为两组,Ⅰ组气管插管机械通气10min后取头低30特伦德伦伯格卧位,20min后开始气腹。Ⅱ组气管插管机械通气10min后开始气腹,20min后取头低30特伦德伦伯格卧位。术中维持气腹压15mmHG、30T位。监测呼吸、血气指标。结果:与麻醉后比,气腹及T位后潮气量(VT)下降、呼气末二氧化碳分压(PETCO2)、气道峰压(PPEAK)增加;肺顺应性(C)下降;气腹所引起的改变比体位所引起的改变更明显。结论:妇科腹腔镜手术气腹(腹内压15mmHg)和30T位可引起肺有效通气量明显降低,其中气腹对呼吸影响更大。
To investigate the effect of pneumoperitoneum and position (T position) on respiratory function in gynecological laparoscopic surgery. Methods: 80 patients were randomly divided into two groups. Group Ⅰ tracheal intubation mechanical ventilation for 10min and then head low 30 Trendelenburg position, 20min after pneumoperitoneum. Group Ⅱ tracheal intubation mechanical ventilation 10min after pneumoperitoneum, 20min after taking the first low 30 Trendelenburg decubitus. Intraoperative pneumoperitoneum pressure to maintain 15mmHG, 30T bit. Monitoring of breathing, blood gas indicators. RESULTS: Compared with post-anesthesia, tidal volume (VT) decreased after pneumoperitoneum and T-position, PETCO2 and PPEAK increased, pulmonary compliance (C) decreased, pneumoperitoneum The change caused by the position is more pronounced than the change caused by the position. Conclusions: Laparoscopic pneumoperitoneum pneumoperitoneum (intra-abdominal pressure 15mmHg) and 30T can significantly reduce the effective ventilation of the lungs, and pneumoperitoneum has a greater influence on respiration.
